Shelter Hall, Brighton Piling Installation for Seafront Revamp
Customer – CJ Thorne
Project duration – 3 weeks
When – October 2015
Type – Sheet piling, Driven piling
Suttle Projects played a key role in an ongoing scheme to revamp a historic section of Brighton’s seafront.
Suttles’ piling expertise was called on by CJ Thorne to help reinforce part of the iconic beach promenade to enable the construction of a new walkway over a larger area.
More than 62m linear metres of sheet piling was driven with specialist silent piling equipment in order to reduce the future effects of erosion on the new infrastructure.
A Giken Japanese-type silent piler was used for the task of driving in the sheets. This machinery uses hydraulic pressure – a different technique to more conventional piling installation. This method prevented structural damage to the nearby Shelter Hall (built in the 1880s), which since 2013 has been undergoing extensive renovation.
Our team used four pieces of plant equipment for the job – an RTG RG16T telescopic leader rig, with drilling attachment (to loosen the ground), a Giken silent piler (to drive in the sheets), a 50-tonne crawler crane, and a Movax side grip rig (to lift and move the piles into place). The Movax proved critical in allowing work to proceed through a period of adverse weather, when the crane could not be deployed. The piled retaining wall was 94nr Arcelor-type AZ26-700 section steel sheet piles.
